2-strand electrical fencing on a pigtail budget

This winter, with all the dry (electrically insulating) snow we have had in Vermont, our attempts to wean 9-month-old calves were thwarted by those who were willing to take a weak hit from the single-strand polywire, in order to continue their habit. We ran a second, grounded polywire just below the hot wire to gain the respect we deserved for our 10kV reading. We did this by wrapping the second polywire around each pigtail, on the conductive metal part, pulling it tight and attaching a little binder clip to keep it from slipping down. Only once did we need to tie a broken ground wire. (Lesson learned) Peace has been restored on the farm
